Summary:Kachari (Cucumis callosus), having English name cucumber pubacent is a warm season annual crop which grown as wild or cultivated at a large scale with bajra, moth, moong and guar in arid and semi arid regions of Rajasthan. It requires 25°C temperature for seed germination and 30°C-35°C for growth and development. During survey, kachari fruits were found infected with Fusarium rot caused by Fusarium pallidoroseum causing severe damage at maturity stage both in quantitatively and qualitatively in the field of Jobner vicinity during Kharif season 2009. The effect of different levels of temperature, relative humidity and pH on growth and sporulation of the pathogen were tested in vitro conditions. Maximum mycelial growth and sporulation were found at 25°C temperature, 100% relative humidity and maximum dry mycelial weight at 6.5 pH.
